I bike in the Winter in Minnesota, so a face mask is often a nice thing to have. This one is comfortable and warm, and was available at an attractive price in a highly visible color I like. My one reservation (making it a 4-star rather than a 5-star product) is that it's a bit short. So if I were to wear it in REALLY cold weather (sub-zero Fahrenheit, for example), I'd need to combine it with a neck gaiter. It's been OK at temperatures above 10 deg F. I imagine it would be really, really good at really cold temperatures if worn over a silk balaclava, but we haven't had deeply sub-zero period since this arrived, so I haven't tested this idea yet. Given the price, I'm quite glad to have added it to my winter gear.
